MMRM: A Multimodal Representation Model for E-commerce Search Ranking
JD introduces MMRM (Multiplex Multimodal Representation Model), aligning multimodal large models with four key collaborative signals in e-commerce:

The goal is to learn decoupled product representations to support multi-task ranking, simultaneously serving different ranking objectives in e-commerce search.
